And in saying that there is no more sacrifice for sins, that means that an attempted “sin atoning sacrifice”, which never existed, will also not exist in the future.

Will there ever in the future be blood-based sin offering for atonement sanctioned by God as it was understood in the old covenant system, e.g., where God says:

And you shall offer a bull every day as a sin offering for atonement. You shall cleanse the altar when you make atonement for it, and you shall anoint it to sanctify it. (Exo. 29:36)
